Marion County Deputies have arrested a man wanted for child rape. Authorities in the east Tennessee had been looking for Joshua Luke Mitchell since last Sunday. Authorities believed he had fled the state, but Sheriff Bo Burnett says Mitchell was spotted by State Troopers Thursday evening on Highway 41. Burnett says Mitchell was arrested shortly before 7:30 p.m. behind the Riverside Catfish House after a short foot chase. Mitchell is accused of raping a four-year-old girl he was reportedly babysitting. He is a registered sex offender in Texas, North Carolina, and Alabama.
